I only just realised as I went to schedule this post that there are five Sundays in April this year so that we have to post Z today. It's a total coincidence that I am growing some Zinnia seedlings, but look, it solves my Z conundrum. I think they came, like many of my home grown plants, as freebies in the Gardener's World magazine. (I will give them a little plug here as it is worth every penny; the website has loads of advice and plant information, and special offers for subscribers, the free seeds every year and free entry to gardens all over the country.)
The kitchen windowsill is the main site for growing seedling, if I put them in Tish's bedroom (that faces east) the cat will often trample on them or even knock them off.
Hopefully, later in the summer they may look something more like this:
Linking back to the A to Z Challenge.
Stay safe. Be kind. Plant seeds now.
