Product description
Living up to its cheerful name, this bright, buttery lemon-yellow variety injects a massive dose of energetic colour directly into the landscape. The towering, heavily flowered stalks create a strong sense of architectural enclosure when planted in tight groupings or rows. It pairs exceptionally well with warm-toned colour schemes, complementing deep oranges, reds, and purples while acting as a highly visible, towering magnet for local bee populations.
To protect the plant during extreme temperature swings, apply a thick layer of organic compost or bark mulch heavily over the root zone to insulate the crown and lock in essential moisture. While it is highly drought-tolerant once established, providing a consistent, even supply of water during the bud-formation stage will result in significantly larger, longer-lasting flowers. At the end of the growing season, once the foliage has completely died back and yellowed, cut the entire hollow stalk cleanly to the ground to prevent it from snapping in winter storms.
Please Note: When purchasing plants, please consider that each live item is unique and may therefore differ from the images shown, which are for illustration purposes only. The plant will be supplied in a growers pot. Depending on season, some plants may be pruned back to encourage growth and deciduous plants may arrive without leaves.
Garden Plant Size Guide

Plants in larger pots can be multiple years older than their smaller counterparts with more mature root systems and foliage. This makes them able to thrive as a full size plant in your garden quicker than smaller alternatives.
The most common size of pot that garden plants come in are 9cm/1L/3L/5L this is in reference to the diameter at the top of the pot.
9cm potted plants still remain the most popular cost effective option though, they just may take a little patience to allow them to grow into full maturity once planted in your garden.
