Lobelia Waterfall 'Blue Improved' flowers for months in summer and autumn, with masses of deep blue flowers on trailing stems. Easy to grow and very low-maintenance, this cottage garden favourite looks lovely trailing from pots and hanging baskets, or growing in pockets in stone walls. The deep blue colour makes a fantastic contrast to bright orange and yellows, and tones beautifully with pinks and purples.

How to grow

Planting in Containers

Plant approximately 6-10 plants per 30cm container. Sprinkle a layer of stone or gravel at the bottom of the container to aid drainage. Use a high-quality young plant or general-purpose compost, spacing plants evenly to allow room for growth. Mix in a slow-release granular fertilizer before placing the plants to provide nutrients. Water thoroughly after planting and continue to water every 1-3 days depending on rainfall, ensuring the container doesn’t dry out.

Planting in the Ground

Dig a hole approximately twice as deep and three times as wide as the plant. If your soil is heavy, mix in general-purpose compost, horticultural sand, and potting grit to improve drainage. Gently compact the soil around the plant and water thoroughly.

Feeding and Aftercare

Use a liquid feed high in potash to nourish the roots directly. Keep plants well-watered during dry summer months, which may require daily watering depending on rainfall.

Guide To Plant Sizes

Seedlings

Supplied in trays of 20’s, seedlings offer great value for money and purchasing at this stage of growth helps when time or space is at a premium. They’ve been started off for you in specialist conditions where heat and humidity controls are needed for optimum plant growth and health. Delivered at the right time of year for growing success, when your plants arrive, simply pot them on and continue growing indoors, before hardening off and planting out in summer.

Super Plugs

Super plugs are larger than seedlings, they have more developed roots so they are stronger and establish faster. Available in select bedding collections, they are cutting raised, which means they come from cuttings and not seeds. This growing process can help create superior plants with many positive attributes including longer flowering times and uniformity. On arrival, pot on, growing indoors, before hardening off and planting out in summer.

Garden Ready Bedding

Supplied in trays of 12 and the largest of our plugs, garden ready bedding plants are seed raised and will be sent to you at the perfect time for planting. They have been grown on to a size where they are ready to plant straight out. Bursting into life, if they have not yet begun to flower, it will only be a short time before they do.
