Samphire grass

Here's the first part of the Growing advice - though you seem to be doing very well without it! :-
Germination Instructions

Sow indoors in spring. Surface sow onto moist, well-drained seed compost. Just cover seed with a sprinkling of soil. Place somewhere warm, ideal temp. 25°C. Germination takes 1-3 weeks approx. but can be erratic. Once seedlings are 2-3cm tall transplant to individual pots of free-draining sandy soil and grow on. Grow on under glass or acclimatise and place pots outside after danger of frost has passed.

Growing Instructions

Prefers a light, well-drained sandy soil in full sun. Samphire is best watered with a saline solution of 1 teaspoon of real sea salt dissolved in one pint (568ml) of water. Do not use table salt as this contains a caking agent which will kill the plant. Due to the plants salty requirements it is preferable to keep Samphire in a container or pot. Samphire is happy in a pot on a windowsill, container planted on the patio or in the garden. Keep the soil moist at all times. Harvest shoots from June-August, after which the shoots become woody.
