With the fluctuating weather this spring, you need to have good sturdy little plants to plant out. If they weren't, they'll struggle, especially if they're exposed to cold winds and wild, wet weather. That sounds the most likely scenario Rob. As fidget says, those plugs are grown in protected environments.
Direct sown seed will be fine, flowering slightly later than a bigger plant in the ground just now, so you'd probably be better buying some seed and getting them in.
