Garden Ready Plants - Our garden ready plants are selected for garden performance, straight from the nursery. We send them to you 'green' ahead of flowering (but please note some varieties may show a few blooms), which means plants will establish quickly and all their energy goes into producing better roots, so they produce more flowers throughout the season.

How to Grow
Lobelia plug plants can be planted directly into flower pouches. For baskets, beds and window boxes, pot up plugs and grow them on in warm, frost free conditions for transplanting at a later date. When all risk of frost has passed, gradually acclimatise lobelia plants to outdoor conditions over a period of 7 to 10 days before transplanting them into their final containers in any, well drained soil, in a sunny or semi-shaded position.

For more information and guidance check out our Gardening Guides.

More Info
Feed and water lobelia plants frequently throughout the summer to promote an endless supply of delicate lobelia flowers. Caution: irritant to skin and eyes.
