I did my cuttings on 14/8/2014
After 9 days, on 23/8/2014 (today), my findings are:
Pot with 4 cuttings and permanently bagged, placed in corner with direct morning sun - ROOTED
Pot with 4 cuttings and permanently bagged, placed in corner and direct morning sun - ROOTED
Pot with 2 strong cuttings with flower spikes, bagged and placed in the office with indirect bright sun all day - FLOWERED (most probably rooted)
Pot with 3 cuttings unbagged, placed in corner and direct morning sun. With added seaweed extract foliar spray - UNROOTED & 1 DIED
Pot with 5 cuttings in clayey soil and open air - ALL DIED
18/18 accounted for.
CONCLUSION:
- Need to bag for around 9 days outdoors
- Morning sun and indirect sunlight are good
- Best not to use seaweed extract liquid fertilizer
- 1:1 peat & perlite potting mix with added worm casting is the best combi
Update: 26/8/2014
Rooted plants survived acclimatising (1h, 2h, 3h, permanently unbagging) as of yesterday. Total of 12 days to root a cutting successfully.
Unrooted plants still did not take root. Had to return them into the bag.
Update: 4/9/2014
1 cutting in the pot with 4 cuttings apparently did not root as previously assumed, and was removed before it could fully rot. The 3 remaining cuttings are doing fine, unbagged, in bright indirect light, away from the rain.

Pot with 2 remaining cuttings is still bagged, in bright indirect light.
Pot with 2 cuttings containing flower spikes have flowered and subsequently deadheaded due to a mealybug found in one flower, and a few black dots found on the other flower spike. I suspect that the black spots are lavender shab. Leaves and stems affected were heavily pruned back.
Here's the picture of the pot with 2 ex-flower cuttings.
