Product description
The Lobelia Upright White pushes out hundreds of tiny, bright white blooms from a tight, clumping base, illuminating the darker corners of a floral display. It is a brilliant, non-hardy gap filler that adds a snowy, textural contrast against broad-leafed plants and brightly coloured vines. Though it is a relatively short-lived summer performer, its sheer volume of flowers makes it an indispensable addition to a heavily packed container.
To keep the foliage looking fresh and the flower buds actively opening, you must treat it like a highly demanding wetland plant. Keep the loam compost consistently wet to the touch, physically preventing the delicate, fibrous root system from ever experiencing drought stress. Consistent, heavy watering ensures the blooms continue to flush without the plant shutting down in an attempt to conserve energy.
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.

Instructions
Top Tip
If the floral display starts to look tired and faded, do not be afraid to be ruthless. Take a pair of sharp shears and chop the entire plant back by half its height. This drastic haircut triggers the Lobelia Upright White to push out a massive burst of fresh green growth and new buds.
How to Water
Hanging baskets dry out rapidly, and this specific filler absolutely hates drought conditions. You must maintain a consistently damp soil environment to stop the delicate root system from crisping up. Checking the basket daily guarantees your Lobelia Upright White will never suffer from fatal dehydration.
How to Plant
Bury the small root plug into the middle tier of your basket using a moisture-retentive loam compost. Make sure you gently tease the roots apart before planting to encourage them to spread outward. Giving your Lobelia Upright White this central spot allows it to act as a brilliant, bushy filler between the taller plants.
