Flowers to sow in April, directly in their final flowering position, include sweet peas. April is also the time to plant out your autumn-sown sweet pea seedlings. 

Depending on the variety, hardy annuals can be sown either indoors or outdoors, following the instructions on the packet. Half-hardy flowers can be sown in trays and kept on a windowsill or in the greenhouse. Browse through our range and pick your favourites! 

Take a look at our propagators and propagation equipment to get the most from your seeds.
