AGAPANTHUS COOL STEEL™
Producing up to 30 purple-blue flower heads per plant from spring through summer, this compact Agapanthus variety transforms dry Australian gardens into a pollinator haven without demanding constant attention. Cool Steel™ thrives in full sun to partial shade across all soil types—clay, loamy, and sandy—making it equally at home in coastal gardens, inland properties, and challenging drought-prone landscapes. Naturally frost-hardy and exceptionally drought-tolerant once established, it maintains architectural green foliage year-round while resisting pests and diseases that plague less resilient cultivars, delivering reliable colour long after other varieties have faded. Simply apply an organic fertiliser feed in late winter and deadhead spent flower heads to encourage extended blooming; no staking, spraying, or soil amendment required. Plant in clusters for maximum impact or use as a low-maintenance border accent in full-sun mixed gardens where deep blue tones will anchor the design.

Frequently Asked Questions
When you shop with The Plant Hub, you will receive free delivery with every full box of plants.
A full box contains 4 items, examples of these are; 4 X Tube 10 Packs, 4 X Lawn Plug trays, or a combination of Tube 10 Packs and Lawn Plugs totalling 4 items.
We ship to NSW,ACT,Victoria, and Queensland, as quarantine is an important issue with the movement of plants across state borders. Due to quarantine restrictions, we cannot ship plants outside of Australia.
This is an excellent question. Live plants require express freight, unlike other products, which may take a week or so to be delivered using non-express freight services. The Plant Hub uses couriers and Australia Post to ship orders. When your plants are dispatched, we will send you an email to let you know how they have been shipped, and you will also receive a ‘Track and Trace’ label number and a link to the relevant delivery website to track the progress of your delivery.
As we deliver 'live plants', we naturally want to ensure they arrive in the best possible condition. We only dispatch orders on Monday of each week (except public holidays) to ensure orders arrive that same week. The cut-off time for orders is 6 pm Sunday. Orders placed after this time will, in most cases, be shipped the following week.
Plants normally arrive during business hours within 2 to 3 days for metropolitan areas. In regional areas, it may take an extra day or so to arrive. If you have ordered plants and have been notified that your order has been dispatched, but has not arrived by Thursday afternoon, don't hesitate to contact our office to track down your order for you.
No, if you would like your order to go to a PO Box, we send your order to Australia Post; however, we ask that you pick up your plants the day they arrive at the Post Office, so you receive your plants in the best condition possible.
