MacArthur™ Bottlebrush (Callistemon viminalis ‘LC01’) Growing Guide
  • Best Growing Environment: The MacArthur™ Bottlebrush thrives as a compact, evergreen shrub in warm, sunny landscapes with good air circulation, making it ideal for Mediterranean-style gardens, coastal areas, hedges, mass plantings, rock gardens, or container accents on patios and terraces. It performs best in well-drained soils of most types (including sandy or clay-loam mixes) and tolerates urban pollution, salt spray, and drought once established, while responding beautifully to chunky mulch that retains moisture and suppresses weeds. This cultivar, a controlled cross between the vigorous ‘Captain Cook’ and compact ‘Little John’ varieties, suits low-maintenance yards where it can attract bees, hummingbirds, and birds with its profuse red blooms without becoming invasive or overly large.

    ozbreed.com.au
  • Botanical Name: Callistemon viminalis ‘LC01’ (also known as MacArthur™ with plant patent PP25,011 or PBR protection). It belongs to the Myrtaceae family and is a selected cultivar of the weeping bottlebrush species native to Australia.

    ozbreed.com.au
  • Common Names: MacArthur™ Bottlebrush, Macarthur Bottlebrush, MacArthur Callistemon, or simply MacArthur red bottlebrush. It is often marketed for its improved flowering and tidy form compared to older bottlebrush varieties.

    plants.franzwitte.com
  • Average Height and Diameter: At maturity, this semi-dwarf shrub reaches about 5–7 feet tall (commonly 6 feet) with a spread or diameter of 4–6 feet (typically 5 feet), forming a dense, rounded, mounded habit that stays neat without excessive pruning. Its low canopy makes it suitable under power lines or in smaller spaces.

    plants.franzwitte.com
  • Growth Rate: It grows at a medium rate overall with vigorous establishment once planted, quickly developing its bushy, tidy form and reaching mature size in several years under ideal conditions. Expect a lifespan of around 30 years with proper care; the compact genetics from its ‘Little John’ parent prevent it from becoming leggy while inheriting faster flowering vigor from ‘Captain Cook’.

    plants.franzwitte.com
  • Sun Requirements: Full sun to partial shade is ideal, with full sun producing the most intense and prolonged red bottlebrush blooms (mid-spring through late fall). It tolerates part shade but may flower slightly less prolifically in heavier shade.

    ozbreed.com.au
  • Cold Hardiness: This cultivar tolerates light frost and moderate freezes better than many older bottlebrushes, making it reliably hardy in USDA Zone 8a and warmer (generally performing well in Zones 8–10 or 11 in mild-winter regions). Protect young plants from extreme cold snaps in marginal zones, but established specimens handle typical winter lows without issue.

    plants.franzwitte.com
  • Water Requirements: Provide regular watering (as needed) for the first 8–13 weeks after planting to help roots establish deeply. Once established, it is quite drought-tolerant and adapts to average-to-moist conditions without drying out completely during peak heat; avoid overwatering in heavy soils to prevent root rot. It performs well with supplemental irrigation only during prolonged dry spells.

    ozbreed.com.au
  • Detailed Fertilizing Guide: MacArthur™ Bottlebrush is low-maintenance and requires minimal fertilizing once established—often none at all in fertile soils. If growth seems slow or foliage pales, apply a slow-release, balanced fertilizer (or a native/Australian-plant formula low in phosphorus to avoid toxicity common in Myrtaceae) in early spring. Use a granular product at the manufacturer’s recommended rate around the drip line, water it in thoroughly, and avoid high-nitrogen formulas that could promote leafy growth at the expense of flowers. Reapply only if needed in subsequent springs; over-fertilizing can reduce bloom quality and invite pests.

    ozbreed.com.au
  • Planting Guide: Choose a site with full sun to part shade and prepare the soil by incorporating chunky mulch after planting to conserve moisture and moderate temperatures. Dig a hole as deep as the root ball and twice as wide, gently loosen circling roots, and position the plant at the same depth it was in the nursery pot. Backfill with native or amended soil (no heavy amendments needed due to its soil tolerance), water deeply to settle, and apply 2–3 inches of mulch keeping it away from the trunk. For hedges or screens, space plants 1–1.5 per linear meter (or 1–2 per square meter for massing). It establishes quickly and works equally well in-ground or in large containers (use a quality potting mix and water more frequently in pots). Prune lightly after flowering (1–3 times per year) to maintain shape or encourage density.

    ozbreed.com.au
  • USDA Zone: Hardy in USDA Zone 8a (and warmer zones up to 10–11), where it remains evergreen and flowers reliably through the growing season. In Zone 8a, provide young plants with winter protection the first 1–2 years if extreme cold is forecast.

This versatile, rust-resistant native shrub offers vibrant red “bottlebrush” flowers against fresh green-to-grayish foliage with a silvery sheen, making it an excellent choice for easy-care landscapes, pollinator gardens, or compact hedges in suitable climates. With its tidy habit and low water/fertilizer needs, MacArthur™ Bottlebrush rewards minimal effort with months of color and wildlife activity.

WHAT A MISTAKE THIS WAS! EXTREMELY SOFT, OFFERING NO SUPPORT AT ALL!
Size: Camping(Pack of 1), Color: Original White, Size: Camping(Pack of 1), Color: Original White
INITIAL Impression: WHAT A MISTAKE THIS WAS! The foam is taking forever to expand, it is a gross color, it is way too soft where it has started to expand. The warranty says it ONLY applies to the original purchaser, which means you cannot give this to anyone as a gift, it would instantly lose its warranty. DO NOT USE ANY EXTERNAL HEAT SOURCE (some memory foam actually suggests putting it in a slightly warm dryer, but to do that would void the warranty.) I got this because I have severe back pain, but it doesn't look like it will ever be firm enough to offer support. It says it will take 24-48 hours to fully expand! I bought it because I need relief NOW, not in 2 days! It has a very limited warranty of only 3 years. The memory foam travel size pillows I bought on Amazon, made by MALOUF, in 2017 came with a 5 year warranty and are still useful, but do need replacing, 9 years later! Unfortunately those pillows are no longer available on Amazon. I chose this small Vaverto memory foam pillow "for camping", because it was available with next morning delivery with some other purchases I made yesterday. (Hoping to be able to use it TODAY.) And because most of the reviews were positive. It says on the crumpled paper warranty and directions, that ONE side of the pillow is for cooling, but WHICH SIDE? They don't tell you. The order "Shipped at 12:31 AM" the box was cold when it was "Delivered at 9:41 AM". The outdoor temperature had climbed to 51 degrees by then from a low last night of 47 degrees. My room is heated to a comfortable 78 degrees. But we still have a long way to go before this hunk of greenish blue, extremely squishy (I can pinch it at the most expanded area and my fingers nearly touch each other with maybe ¼” of foam separating them. NOT an encouraging sign. There are bits of foam starting to come out of the "punched holes" which appear to be slightly smaller on one side than the other, but WHICH is supposed to be the "cooling side that dissipates heat? Probably the larger holes, but they also weaken the firmness. On closer examination of the crumpled paper that came with it, it says '"TWO-SIDED COVER FOR VERSALITY" Then in a tiny diagram next to that, it says "COOLING SIDE DISSPATES BODY HEAT" with Dissipates spelled wrong! Where is this thing made? Ah.. "CHINA" on a severely crumpled tag inside the cover. It also says the cover is “70% Polyester 30% Viscose Made from Bamboo”. But the Photo shows "Bamboo" in large green letters on the cover along with "VaVerto" in much LARGER grey letters above that. The only letters on my case are the bottom part of a "b" with two "oo" next to it, in a grey-green color, extending from the side seam. NO actual WORDS at all. And the cover looks identical on both sides. Okay, it's been well over 4 hours in a very warm room, now 80 degrees with the sun pouring in, and it has mostly expanded, but I can still almost touch my fingers together when pinching the thickest part of the pillow, there is still only about ¼” of foam between my fingers. I would describe that as EXTREMELY SOFT. In the actual description of the product, on the Amazon page, if you open the "Features & Specs" it shows "Item Firmness Description - Medium" NOT what the headline says for the product: "Vaverto Small Memory Foam Bed Pillow for Camping - Compressible Medium Firm, Breathable Cover, Machine Washable, Ideal Backpacking". If I weren’t bedridden in a nursing home this would go back immediately, but it is very hard to get the staff here to help me return ANYTHING that needs to be taken to a store or kiosk. So I may just be out $22.07. FINAL Impression: WHAT A MISTAKE THIS WAS! EXTREMELY SOFT, OFFERING NO SUPPORT AT ALL! (PHOTOS ARE NOT ACCURATE to the product!!)

Comfy, but not Cooling
Comfy for a stomach sleeper, but doesn’t stay cool as promised by other reviews.

Meh. Not impressed but not the worst.
Size: King (Pack of 1), Style: Single Pack, Size: King (Pack of 1), Style: Single Pack
TL;DR: Not worth the money I’ve had quite a few cooling pillows and, while not the worst, this is also not the best in my experience. First, I had to take the cover off. It was ridiculously thick, thereby negating any cooling effect that I could feel. With the cover removed, the cooling sensation is noticeable when laying your head on it and it lasts for a minute or so. On the bright side, when the cooling feeling completely dissipates, the pillow doesn’t feel hot like some others. Having to lay on it without the cover makes it less comfortable because of the encasing material. Other than that, I’d rate the support and comfort as mediocre as well. Not worth the money in my opinion, maybe if it was about 33%-50% less.

Firm yet comfortable
We have purchased several of these pillows over the past few years. They have held up well and held their shape and firmness, even with washing. They are the right height for neck comfort and we do not need to double up pillows anymore to get a good night's sleep. They are also a good firmness to rest against while sitting up in bed.
