Q.Companion Planting For Lavender In A Wooden Raised Bed ?
Hi. I want to plant lavender seeds from a package. I was wondering if I plant them in a wooden raised bed on both sides of my driveway. Was thinking cause they are really purple lavender, possibly planting tulip bulbs or poppy seeds with them? Is this possible. A mixture of light purple, pinks,whites & orange. I’m in zones 2-6, Ontario Canada, near Manitoba border. Seeds are from Burpee’s, Lady Lavender or English lavender, have both seed packages. Raised garden boxes are 2 ft wide,by 9 ft long, x2. On both sides of my driveway. Driveway is 18 ft long. I have a deep ditch both sides of my driveway, with a repurposed multiplied coloured ladders which have metal rungs. I’m using them as a border instead So people won’t drive into the deep ditches. So I wanted to put the raised garden boxes on the inside of driveway. With the lavender & the multiplied tulips or poppies with them. Could you help me please? I can’t put the lavender in the ground, due to I’m renting my house, so this is my solution they said they would accept. (Landlord)

Lavender is very particular, it needs dry, well draining soil and full sun. In Ontario, you will need winter protection for it if a lot of snow and ice is expected. Lavender originated from the Mediterranean region which is hot and dry. Purple coneflower would be beautiful with it. It's more pink looking.
California poppies are suggested in the second article. Tulips would only bloom in the spring, but you could try them in one area. They would need more moisture than the lavender so I wouldn't spread the tulips among the lavender. Here is more info:
